Hex Mayflies
Hexagenia limbata
The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

Hardly any Hendrikson's - saw 1/2 a dozen early then none for rest of day. Some Grannoms and also tan caddis. Once in awhile there would be a rise but for the amount of sun and caddis there was very little surface action. |

Two larger fish on top, all others on mymphs, either a #14 BH PT or a #16 olive caddis with a gray ostrich herl thorax and lemon woodduck downwing.
It's a shame such pretty water and so few mayflies and rising fish.
